Earth-48

Earth-48 is the native home of the Forerunners, creatures bred by the Monitors from all the alien races of the solar system after the destruction of all human life on Earth (now called War World) in a war against other planets. Forerunners are matriarchal, telepathic through their eldest living female, living in a society that kills off the weakest of its kind, and unaware of what happens outside of their solar system.

While human characters are not present, alternate versions of extraterrestrial characters such as General J'onzz, Jemm and Starman also exist.
